A Florida textbook publisher removed all references to race from a lesson about Rosa Parks, the Alabama civil rights hero, in an effort to get its books approved by a Florida committee, The New York Times reported Thursday.

The state is in the middle of reviewing social studies curriculum.

Florida requires schools teach Black history. But a new law signed by Gov. Ron DeSantis prohibits instruction that would compel students to feel responsibility, guilt or anguish for what other members of their race did in the past, among other limits. Some publishers felt caught between the two guidelines and increasing political attention to school textbooks.

One publisher, Studies Weekly, is used in 45,000 schools across the country, according to its website, including Florida elementary schools.

The New York Times compared three versions of the company’s Rosa Parks story, meant for first graders: a current lesson used now in Florida, an initial version created for the state textbook review and a second updated version.

In the current lesson on Rosa Parks, segregation is clearly explained: “The law said African Americans had to give up their seats on the bus if a white person wanted to sit down.”

In an updated version created for review by Florida’s textbook committee, race is not mentioned at all.

“She was told to move to a different seat,” the lesson said, without an explanation of segregation.

Studies Weekly cited Florida’s new law as its reason for changing the lesson, the Times reported.

The Florida Department of Education suggested that Studies Weekly had overreached. Any publisher that “avoids the topic of race when teaching the Civil Rights movement, slavery, segregation, etc. would not be adhering to Florida law,” the department said in a statement, as reported by the Times.

The company’s curriculum is no longer under consideration by the state.
